Prostate cancer treatment with high-intensity focused ultrasound

High-intensity focused ultrasound, so-called HIFU therapy, destroys cancer cells by heating them to high temperatures. Prostate tumor-shrinking is achieved thanks to precise ultrasound wolves targeted at the specific point, while nearby organs and tissues remain intact. The manipulation is performed through the rectum without incisions under gentle spinal anesthesia. In this case, the patient is conscious but feels nothing below the waist. If necessary, the doctor can add sedatives to relieve stress. The patient is placed on a table, and the surgeon inserts a gel-lubricated sensor into the rectum. Under ultrasound control, the doctor outlines the impact zone with an accuracy of 1 mm. Then it starts the HIFU therapy process. First, ultrasound waves heat the tumor to a temperature of up to 80-100°C, destroying cancer cells. Next, the doctor controls the process through the display, adjusting the probe position and pulse power with a joystick. The treatment duration depends on the lesion volume. Usually, it takes two to three hours. HIFU excludes the side effects of surgery: bleeding, urinary incontinence, and the recovery period is significantly shorter.
